Shouldn't that be the USDM? JDM has no egr does it? Or do you mean that on the JDM it would have to pull the timing back in situations where the EGR would have been active if it were present?

If the JDM had EGR it could run more aggressive timing such as the USDM does when the EGR system is active.

I suppose, as you say there isn't any real power discrepancies between markets, the benefits would be limited to USDM owners just being able to remove the EGR both physically & "mentally" from their car...

As I said, it may be worth it just for the properly tuned timing maps.

Nope, same chip IIRC.
